Don't be absurd. There is a ginormous difference between a party whose position is that climate change is a problem that we have to deal with but doesn't support all possible ways to deal with it, and a party whose position until recently was that climate change was a hoax perpetrated by China or socialists or others to destroy the US, and whose current position is that maybe it is happening but we should not take any action and in fact should increase our fossil fuel use.
